Fig. 5From: Airway epithelial cells exposed to wildfire smoke extract exhibit dysregulated autophagy and barrier dysfunction consistent with COPDDifferentiated primary human bAEC secrete IL-6 in response to WFSE. Differentiated air-liquid interface cultures of primary human bronchial airway epithelial cells were exposed to increasing concentrations of wildfire smoke extract (WFSE) for 6 h. The secretion of IL-6 was significantly increased from bAEC treated with 5% WFSE vs. the control exposure. Intervals are standard error. **, P ≤ 0.01 for n = 3 experiments using cells derived from different participantsBack to article page
